The $15 hanging fee enables you to submit up to 3 books.
Paying this fee is the first step of registration.
If you wish to submit more than 3 books change the quantity in the cart.
Or you can decide later and come back and pay again.
NOTE: PayPal simply processes the payment, you do not need a PayPal account.
But if you strongly object to PayPal, email firstname.lastname@example.org and we'll figure it out.
